The stunning jewel appeared to feature a large champagne diamond surrounded by a series of smaller diamonds.

She later shared a picture of herself with her hand raised – showing off the ring in the process.

The Sun Online has contacted Rihanna’s rep for comment.

Rihanna is believed to have been daring Hassan for over a year and they managed to keep their romance a secret for almost for six months before they were snapped enjoying a steamy kissing session in Spain over the summer.
